On July 19, 2012, I spotted a tall Bigleaf Maple in the Coast Redwood forest near Avenue of the Giants at Humboldt Redwoods State Park. My next visit in October 2012, I spent a morning for accurate measurement using an Impulse 200LR laser rangefinder mounted on a tripod.

This Maple was named "Humboldt Honey" ... The measurement using the Impulse 200LR rangefinder was 157.80 feet for height The trunk circumference was 9.50 ft..

That established this as the tallest known of the Acer (maple) genus in the United States, and apparently in the world. In other words, it's the tallest known of all the species belonging to the Acer genus.

Washington had one reported around 160 ft. once, but reliable sources say it's closer to 148 ft..

The tallest in the east USA is a red maple measured at 143.6 ft. (2007) by Will Blozan & Jeff Riddle. That one was in the Great Smokey Mountains.

More discoveries should be out there for the finding.

Why was "Humboldt Honey" named Humboldt Honey?

It's a simple connect-the-dots thing related to scouting portraiture locations, plus the woman shown in the image to the right, photographed the day after the discovery, in both Eureka, and near where the maple grows.

The photo below shows trunk, leaf and laser aimed to top. The 149.98 is just the amount of trunk above the laser. For other tallest finds, take a moment to read other discoveries.

In November, 2012, I returned when golden autumn leaf color provided a better opportunity to look for a taller stem or branch. That trip confirmed that the tallest part of this maple was measured during the earlier October visit.

I also found a 143 ft. maple during the November, 2012, trip. And that not more than two miles away, also along Avenue of the Giants. The next tallest I'm aware of in the Coast Redwood parks is about 130 ft., near Founders Grove.

Out of curiosity, I checked out the flat at the bottom of the trail in Redwood National Park. There's a big group of large Bigleaf Maples there. Most were only 80 to 100 ft.
